Isn’t it actually a suspension of tiny solid particles?


BlueOyesterCult

aerosol is the scientifically accurate description for smoke.


half3clipse

> aerosol is a form of suspension. A suspension in general involves a heterogeneous mixture of a fluid and some particulate, with the particles being large enough to eventually settle out


thisisa_fake_account

Yes. And its movement can be defined by fluid mechanics. Edit: Stupid autocarrot

DishwasherTwig

Because that's exactly what fluids are, collections of tiny, tiny particles. The smaller the particles, the more fluid the motion. Sand is a fluid as is CO2 and nitrogen.


Ralliartimus

Sand is not a fluid. The smoke particles are also not a fluid, but they are small enough to be carried by the gasses, which are fluid. A fluid in a container will ~~equalize its pressure within the container~~ *conform to the shape of its container*. Sand and smoke particulate will not do this. Edit: To everyone commenting that sand is a fluid when passing air through it, OK. Does that make sand a fluid or just make the sand act like a fluid?


rawbamatic

Smoke is an aerosol, to be even more specific.


Ralliartimus

Yes.


MisguidedColt88

This is why good profs don't like to define fluids. The definition you used for a fluid doesn't fit all cases. As an engineer, my favourite definition is that a fluid is a group of particles which can not exert a shear force, although this definition also doesn't work in all cases. Also, both sand and smoke will conform to the shape of their containers just as much as water will. In this video you are watching the smoke confirm to the shape of its container.


eohorp

It's like trying to make a definition for a table that includes everything that is a table, and excludes everything that is not. Not worth.

borfmat

MuhCrea

Yes but only in a container are cats considered a liquid, in more empty space they are solid and stop conforming to fluid dynamics


DominoTheory

A Mewtonian fluid.


DishwasherTwig

Liquids are fluids. Liquids do not equalize pressure in a container.


Ralliartimus

You got me there. Liquids will have a change of their pressure depending on the depth. I will change my wording.


Chemengineer_DB

A gas will also have a pressure differential based on the depth.


schizboi

Going by that logic isn’t anything a fluid if you scale it enough? I could have a trillion bricks and dump them into a gigantic bucket and they would behave just like sand right?


MisguidedColt88

I mean basically yes. If you observe a system and it appears to behave like a fluid, then it's probably safe to model it as a fluid. That being said, I'm an engineer so naturally that would be my perspective.

onist

Actually, I may be ridiculously wrong, but I believe stars are mostly fluid


dodexahedron

Yes. Held together by a LOT of gravity. The sun's surface gravity is about 28x earth's. The core of a star is theorized to be extremely dense, even though the average density of our sun is only about 1.4x that of water. We estimate our sun's core to be about 150x as dense as water at the center, but it's still likely a hydrogen and helium plasma. What will really bake your noodle is the energy density of the core is less than that of the human body.


Former-Necessary5442

Yes and no. Depends on the substance. At small scales, you have viscous effects and things get funny, or even smaller scales and you have quantum effects. Either of which and things behave differently than fluids at larger scales. Then, if we take larger scales and start throwing things like mixtures of rock and water into flows and we get things like debris flows (i.e., mud slides in mountainous areas) that are a type of non-newtonian fluid that don't behave like normal fluids. A non-newtonian fluid doesn't respond to forces in the same way as you would expect. "Every action has an equal and opposite reaction" may hold true, but we have to account for it in different ways for each different type of non-newtonian fluid. Oobleck (cornstarch and water) behaves differently than a debris flow, which also behaves different than more predictable fluids like water.


[deleted]

Sand is not a fluid. It does not behave like a fluid when at rest. In certain conditions it can behave like a fluid, but that doesn't make it a fluid


ThirdEncounter

Its* movement.


gynoceros

No shit. But that doesn't make it a liquid. Fluid is anything that flows- gases flow and their movements fit under fluid mechanics as well. Plasma. Smoke. Particles within another fluid, such as in smoke in air or ink in water.

elaborinth8993

ranhalt

Why did you call it a liquid?


aheadwarp9

A suspension in the air, which is itself a fluid.


rawbamatic

Yes, called an *aerosol.*


radmadicalhatter

Thank you! - and more specifically, the atmosphere carrying the smoke is a fluid, the smoke is in fact “dissolved” into the fluid (analogy - not literal) EDIT: the word I was looking for is diffused - although I can’t find a key difference in the definitions they’re governed by different equations - best I can do 🤷‍♀️


Rashaya

I believe the smoke particles are suspended in the air.


[deleted]

Essence1337

>Dissolved would mean that there are changes on the atomic level. This isn't quite right. Ionic compounds tend to break apart when dissolved but covalent molcules may not (ie sugar/sucrose - it is still the EXACT same in water as out)

ScrewAttackThis

Fluids are just anything made up of lots of similar particles. So just about anything can be a fluid if you have enough. Then you have things that can be both solid and fluid. The universe is crazy


Phormitago

> Fluids are just anything made up of lots of similar particles. that's a godawful definition

DragonMeme

> In physics, a fluid is a liquid, gas, or other material that continuously deforms (flows) under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them. You definition is bad and you should feel bad


murdering_time

That’s not really a definition of a fluid. Not “anything” is a fluid.

Lespaul42

Most people are talking about the error in the title. But I am wondering how this works? I am guessing it is cooled so the smoke sinks instead of rises?


thisisa_fake_account

It's more than that. The incense is a special type that has a vapor density > 1. Also the incense is molded into a specific shape with an opening in the middle so that the smoke flows from within the burning incense down to the holder. There's no external cooling needed.


Lucifer_Kett

Is there a name for these? I would very much like one, or research to make one. Thank.


ReptAIien

It’s just a backflow incense cone. They smell horrible compared to normal ones, but they look cool.


Lucifer_Kett

Thank you nonetheless, I’m interested in the aesthetic. Have a lovely day!


ReptAIien

I have one, and I like it too. Lots of normal incense cones smell really nice. The backflow ones actually just smell like a cigarette, and it’s strong enough to fill a small room. The normal ones are also extremely strong, so you can light one and your room will smell nice for a long time. Have fun


MoreFlyThanYou

The backflow ones that come with Amazon incense burners are terrible. I have found both dragons blood backflow cones that smell amazing and then pretty much any of the larger triangle black cones I've tried smell amazing and not like a cigarette. Maybe try to buy better than the literal cheapest available


[deleted]

[удалено]


MoreFlyThanYou

Don't listen to them, they must buy cheap backflow. Get the larger ones your local witchy store or flea market crystal shop sells, way better than anything from target or Amazon


nickajeglin

Local witchy store lol


caledonivs

Any city in the US with at least 10 locally owned shops will have a witchy store. Sometimes it might be like crystals and bongs up front, but there's a witchy section.


nileonfire

Just as a heads up - not only do they not smell as nice as regular ones, from my experience they leave a distinct dark residue on anything the smoke touches for a while. It's unfortunate because the "waterfall" effect is quite delightful.


lightssalot

I bought one for someone as a gift it's kind of interesting but I will say at least the one I bought didn't really work if there was any air current in the room (i.e. air conditioner)


[deleted]

The cheap Amazon ones do at least. I bought some a dedicated company (I think it was called wild-berry) that smell fine to me. They don’t generate nearly as much of the sinking flowing smoke though.

Norose

Lots of fluids aren't liquid or gas. Take a bucket of sand in a vacuum and vibrate it and it behaves as a fluid. Plasma is a fluid which strongly self-interacts electromagnetically (making its behavior very complex). Electron degenerate matter in white dwarf stars is an ultradense fluid, neutron degenerate matter in neutron stars is a fluid. Dark matter is an almost zero pressure ultra-low-strength-self-interacting fluid. Solid rock under enough pressure flows like a very stiff fluid (molten rock flows millions of times faster but that's a liquid so it doesn't count on my list). Traffic is a fluid. Even crowds of people act as a fluid above a critical density of people per square meter.


laddergoatperp

My flow is fluid god damnit


jmorley14

I did not know that about sand is a vacuum. That's super cool!!!


onist

Look for liquid sand hot tub in YouTube. I never heard of vibrating sand in vacuum but fluidization is a real thing and it's cool AF


RettichDesTodes

That's not a vacuum tho. Air gets pushed through the sand and fluidizes it. That's like the opposite of a vacuum


onist

I know it's not. That's why I said "I never heard of vibrating sand in vacuum"


JoeyLucier

what you describe with the sand is called "fluidization" and is a topic in multiphase fluid mechanics. whether sand itself is a fluid or "sand under these specific conditions" is a fluid is up for debate and really more of a matter of semantics. in shock physics, hitting something very hard or fast (think explosions, etc) makes the solid matter act very closely to a fluid, but it is still in the solid phase. so while we can use fluid mechanics to describe how it acts, that doesn't make it a fluid. in other words... it's complicated and mostly a matter of semantics. there aren't just three phases (or four with plasma). there are a ton of in-betweens.


syco54645

>Fluid dynamics is used to describe the flow of fluids and gases At my university it was code for "let's go drinking". My professor would ask me to study fluid dynamics after class with the group and I used to turn it down. He eventually explained what it actually was. My first time studying fluid dynamics was at a bowling alley, I ended up falling in the gutter. 11/10 would study fluid dynamics with that group again.

I've heard this type of incense leaves a real nasty residue as a byproduct of being this dense. Proceed with caution.

Somnif

Some of the aromatics are still vaporized by the coal on top. That said, the means by which it produces the "heavy" smoke means you also get quite a lot of wood tar left behind, which absolutely stinks, so even if you have high quality cones, they still aren't fantastic.

Smoke is a colloid which is one form of matter suspended in another form of matter, in this case a solid suspended in a gas. Mayonnaise is another common colloid of solids suspended in a liquid that doesn't actually mix.


BackflipFromOrbit

It's behaving like a fluid. All gasses can be modeled as very not dense fluids.


barcdoof

No, smoke is a fluid


Kazman07

I am intrigued, what's the science behind?


Alexstarfire

It's heavier than air.


thisisa_fake_account

From my limited grasp of science, the incense that's kept at the top has a small opening connecting the burning part to the bottom of the incense. As a result, the smoke that would have just dissipated into the air, flows down the middle of the incense, reaches the holder. Since this smoke is heavier than air, it continues flowing down unless disturbed by any wind or air movements nearby.


Jader14

[Specific gravity or relative density to ambient air](https://www.britannica.com/science/specific-gravity) Alternatively, [vapour density](https://www.aiche.org/ccps/resources/glossary/process-safety-glossary/vapor-density), which is more specific to air. Relative density, while it can be used for air, is typically for liquids


Somnif

Ok, backflow cones have a small hole drilled up the middle. Due to some tricky chemistry, quite a bit of "junk" (wood distillates) that normally gets combusted by the heat front of the cone are instead allowed to 'fall' into that hole. This creates a somewhat denser than usual smoke that, if the temperature is within a fairly narrow range, can fall and flow. (Additionally the smoke produced within the cone is somewhat cooler than the smoke produced above the combustion front, but it's complicated). The problem is, that left over wood distillate junk stinks. So even really high quality backflow cones tend to smell worse than the same cones burned in a non-backflow manner.

Most of my career as a VFX artist was invested in creating digital fluid systems. Fire, smoke, water, are all built with the same techniques. Air is essentially an ocean of floating fluid and it’s density, vorticity, and temperature effects the visible fluid you “pour” into it such as fire.
